Hurricane Maria left medical facilities on Dominica "worse than in a war zone," according to the country's leader.

The Caribbean island's main hospital has been without power since the Category 5 storm hit late Monday, killing at least 15 and injuring many others.

Prime Minister Roosevelt Skerrit said the facility's intensive care unit had been destroyed and dialysis machines were down. The backup generator at the Princess Margaret Hospital in Roseau, which is located on the southwest coast of Dominica, was also flooded during the storm.
